Column links in apex

Question

hello,
I have a report in apex. the report shows first name, last name and telephone number.
I wish to add another column - a link to other page to change the telephone number. but I want the link to be shown only for people who alredy have phone number.
for example:
first name: last name: telephone: link:
Jon White
Bill Smith 11111 edit(as link)
I know how to add a column link, and I can write in the Link Text #telephone# but then the result will be:
first name: last name: telephone: link:
Jon White
Bill Smith 11111 11111(as link)
Do you know how can I do it?
(btw I use apex 2.1)

Answer 1

Try with a query like this.
select fist_name,
last_name,
telephone,
decode(telephone,NULL,' ','Edit') edit
from emp;
in the url: replace the page number (27) and the page items as you need.
Mario.
